Issue with tabs on IdP/SP detail page

I've run into this somewhat complicated UI issue a few times.

This issue happens after adding or deleting an admin, or consuming an admin invite.

After any of these actions, the browser is redirected to the same page with #tab-admins added to the URL.

When I then do any page-modifying action on other tabs (like adding an endpoint or even trying to search for users to add as contact), the UI jumps to the admin tab - which looks very confusing. (And makes me forget what I was about to do).

Possible (unexplored) fixes:

• avoiding the redirect to / rewrite with #tab-admins in the admin tab actions
• rewriting the URL back after switching to the admin tab (dropping the tab specific anchor)
• dropping it when switching tabs in the UI
• changing actions on other tabs to force their own tab?
